How to switch from Ksplice to KernelCare in a single step
Ksplice is a technology that updates kernels with important security patches without the need to reboot. After its acquisition by Oracle, it is now offered as part of the Oracle Linux Premier Support. KernelCare is distribution-agnostic and supports Oracle Linux kernels, as well as CentOS, CloudLinux OS, Debian, RedHat, Virtuozzo, and others. Many customers come to us wanting to switch from legacy Ksplice to KernelCare.
The typical process is simple and straightforward:
- Uninstall Ksplice
- Install KernelCare
Can it be even simpler? Of course it can, because the above forces you to figure out how to uninstall Ksplice, and we don’t want you to go that far! So, we have created a script instead. All you have to do is run it and not only it will make sure Ksplice is fully uninstalled, it will also install KernelCare for you in one shot. All without a reboot!
Download and run this script:
Run the command:
bash ksplice2kcare [YOUR KERNELCARE KEY]
If you are using IP based licenses, run:
bash ksplice2kcare IP
The script will check for two letters “IP”, and assume IP based license in this case.
